The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for our local stretch.
Honestly, I’m looking at a bit of a flat spell to kick things off. We’ve got a solid run of days with nothing really worth paddling out for. The first real glimmer of hope doesn’t show up until Tuesday, the 1st of September, and even then, it’s just a whisper of surf. The wait is a good eight or nine days after this Sunday morning.
The pick of the entire outlook, and the only time I’d get excited, is Monday, the 7th of September. Kennebunk Beach is the only break in the game here. Monday morning, the swell is from the SE at 4 ft, with a period of 11 seconds. That’s groundswell, so it’ll have some proper energy behind it, and the combined energy is a solid 478 – that’s strong wave energy. The wind is light and cross-offshore, which means the face will be clean. It’s a fairly consistent spot, but it is sheltered, so it takes a good direction to light it up. This SE swell is the direction it likes, so that’s a good sign. The only bummer is that crowds are sometimes around, so you might have some company.
Before that, the 1st and 2nd of September offer a little bit of life. On Tuesday morning the 1st, we have a 2 ft SE swell with a 14-second period – that’s very long period groundswell. The energy is moderate (120), and the wind is clean and cross-offshore. The waves will be small but clean. Wednesday the 2nd is similar, with a 2 ft SE swell, 12-second period, and a light offshore wind in the morning. The energy is up to 159. Both days are surfable but very ordinary. The water temperature anomaly is about average for the time of year, so nothing unusual there.
The rest of the run is mostly small, poor surf with onshore winds. The 5th and 6th of September show some better wave energy, but the wind is a bit strong or the period is short, so it’s still not a standout.
So, if you’re keen, mark your calendar for Monday the 7th of September. It’s the only real standout. The 1st and 2nd are okay for a quick paddle but nothing to write home about. Get out there if you can.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
